Why Does an Americano Taste Bitter? Espresso Beans Explained

Does Americano Taste Bitter? What Changes the Flavor

An Americano is espresso diluted with water, usually in a ratio of about 1:4 to 1:6, so bitterness depends on the espresso itself. Because no milk softens the cup, the bean flavor comes through directly, and an over-extracted shot reads harsh and bitter, while a balanced shot tastes sweet and rounded. Using 40 grams of espresso with 200 grams of hot water gives a 1:5 ratio many drinkers find balanced.

The bean and the extraction both matter. A dark roast tends to push the cup toward a mellow, bitter tone, whereas a lighter roast brings more acidity. Stale beans lose aroma and crema, so freshness is the first variable to fix. If a bitter americano keeps appearing, shorten the shot, grind coarser, or lower the brew temperature before blaming the beans.

Espresso refers to the concentrated liquid extracted using an espresso machine. In most cases, espresso concentrate is not served directly on its own. Of course, sometimes some customers, for the sake of alertness and a strong taste, will order espresso, but this situation is uncommon. Espresso concentrate is brewed at a ratio of 1:2, so its strength and flavor can be imagined.


Espresso Splitting


When water is added to espresso concentrate, it becomes what is commonly known as Americano. When milk or milk foam of varying textures is added, it becomes a latte or cappuccino, commonly known as milk coffee. Both Americano and pour-over are called black coffee. The difference is that Americano is espresso concentrate with water added directly, while pour-over is brewed from coffee grounds using pour-over equipment, without needing an espresso machine, and without the process of dilution with water. Now let's talk specifically about Americano.

 

How is Americano made?

 

Americano can be said to be the simplest espresso coffee, because Americano consists of only two parts: espresso and water. Iced Americano has the addition of ice cubes. But don't relax just because Americano is simple—the simplest part is also the part that tests skill the most. Americano is often the espresso coffee that best tests a barista's espresso extraction technique.

Compared with milk coffees like lattes, Americano, because it lacks the influence of milk on the coffee's flavor, is the best way to perceive the flavor of the coffee beans themselves. Many barista friends choose Americano when visiting other cafes—firstly because it is convenient and quick, and secondly because it reveals the standard of the establishment.Back to the point. We just said that making Americano is simple, with only water and espresso as its two components, so all you need to do is pour the espresso into the water. The espresso portion needs to be extracted according to the characteristics of the beans, and different beans have different extraction parameters.

 

When making hot Americano, you need to preheat the cup with hot water, then pour in the hot water, and finally pour in the extracted espresso. The ratio for Americano is generally between 1:4 and 1:6. If you prefer a rich, balanced taste, you can choose a 1:5 ratio, that is, 40 grams of coffee liquid mixed with 200 grams of hot water.

Similarly, when making iced Americano, pre-chill the cup with ice cubes, then pour in water, and finally pour in the espresso. Because ice cubes need to be added, iced Americano uses a 1:7 ratio: 40 grams of coffee liquid mixed with 280 grams of ice-water mixture, of which 180 grams is ice and 100 grams is water.

   

Why does Americano taste bitter?

 

Many customers also report that they have had bitter Americano, so does Americano taste bitter? In fact, besides bitterness, coffee also has acidity and sweetness. Through our sense of taste, we can perceive coffee's sourness, sweetness, bitterness, and saltiness, and factors such as different varieties and processing methods affect the proportion of these flavors, making it easier for us to perceive one or several of them.But if excessive bitterness appears in Americano, what could be the reason?

Reason one:The flavor of the coffee beans themselves

 

Black coffee like Americano is mainly influenced by the flavor of the coffee beans themselves, so the first reason Americano tastes bitter may be that the espresso beans chosen are themselves predominantly rich and heavy in flavor.

The rich flavor of espresso beans comes from the taste of their origin and a relatively dark roast level. For example, Front Street Coffee's Classic Blend combines Brazilian coffee beans with Mandheling coffee beans. Mandheling gives this blend its main base of dark chocolate, spices, and caramel; Brazil provides nutty notes and higher body; and a small amount of Robusta is responsible for increasing the espresso's crema. Through a medium-dark roast level, it gains a wonderful sense of balance, with relatively low acidity and a rich, aromatic roasted flavor.

If you cannot accept the bitterness of coffee, then buy Front Street Coffee's Strawberry Candy Espresso Blend.Unlike traditional dark-roast blends, Front Street Coffee's Strawberry Candy is a blend coffee created specifically for espresso and moka pots. It uses a medium roast and combines single-origin coffees from three major producing regions: Costa Rica, Ethiopia, and Colombia. Its flavor features delicate rose, grape, dried fruit, and almond aromas, with a creamy smoothness. The Americano is sweet, bright, and refreshing, suitable for friends who do not like bitter coffee.


 

 

Reason two: Over-extraction

 

Besides bean selection, the bitterness of Americano also comes from mistakes during extraction, such as uneven extraction caused by channeling, or over-extraction caused by grinding too fine.


Lungo Espresso 

 

To ensure the stability of the coffee and that the coffee tastes within the ideal range every day, baristas need to adjust the espresso parameters before opening for business each day, making adjustments according to the daily condition of the coffee beans. For example, today's parameters are 20 grams of coffee grounds extracting 35 grams of coffee liquid with an extraction time of 25 seconds. Compared with the previous 20 grams of coffee grounds extracting 40 grams of coffee liquid, today's parameters reduce bitterness by reducing the tail end, achieving a more balanced flavor.

American Coffee Bean Recommendations


What is the core of Americano? It is espresso. Most of the flavor of espresso coffee comes from its espresso portion. Lattes, Americanos, and others are all coffee drinks heavily influenced by the flavor of espresso. The flavor of espresso comes first from the choice of espresso beans, and only after that is it affected by extraction, so choosing good espresso beans is very important. If you want to easily make an Americano as delicious as those in cafes, Front Street recommends using an espresso blend.
